Suppose a region’s workforce of 14 million is initially split equally betweentwo cities, x and y. the urban utility curve peaks at 4 million workers, and beyondthat point the slope is$3 per million workers. the initial equilibrium utility level is$60. supposed city experiences technological innovation that shifts its utility curve upward by $12. (a) draw a pair of utility curves, one for x and one for y, and label the positions immediately after the innovation (before any migration). you do not need to draw the utility curve to the left of 4 million population. (b) how do workers in each city respond to the innovation.
